If it isn't eating yet, do the best you can to give it light. It will need the nourishment to regain strength. Also you said the mouth was wide open.Is it still open, and if so is the tissue surrounding the mouth firm or slack ? If slack, when you look inside do you see white noodle like stuff ? BTW re inflating is a good sign, it may have just deflated to evacuate waste, they do this through the mouth. If it is inflated, with a closed mouth. It would be best to just leave it. It will find a comfortable spot and settle down until it decides to move again. Handling can be stressful, but you can run your fingers lightly through the tentacles without causing a problem. I know most fish stores wont mention this, if they even know, but its better to have your nem settled into the tank and doing well before adding a clown. Clowns can be stressful, with all the attention they devote to the host.
